Evolution of Water Organisations in England and Wales
Although by the early 1960's there was in existence a large body of legislation dealing with water matters, the Water Resources Act 1963 provided for the first time a significent...

Comparison of Minimum Instream Flow Needs
A sound determination of Instream Flow requirements is facilitated by the use of a physical habitat versus streamflow relationship and the analysis of instream flow benefits produced when...

Instream Flow Needs to Protect Fishery Resources
Numerous methods have been developed over the past several decades to assess the effects of flow regulation on fishery resources and to provide a basis for the determination of suitable...

Benefit-Cost Evaluation of Minimum Instream Flows
In many cases, determinations of minimum desirable instream flows (MIF) are made without full consideration of economic costs and benefits. Benefits are frequently quantified in nonmonetary...
